I have a 180 with a Black Angel, Koran Angel, Maroon Clown, Brown Tang, Sailfin, two different wrasses, yellow headed sleeper goby, and blue spot goby. The clown will not leave the two angels alone. Especially the Koran, which is a juvenile. I had ick in the tank, and removed all fish for 8 weeks. I introduced the Angels back in first and waited a couple weeks before the clown was put back in, just because of his aggression before. He is not a large fish and is dwarfed by the size of the angels, but he still won't let up on them. He is a beautiful fish, but I'm tired of him having the two angels corraled to one half of the tank. I know they are considered one of the more aggressive clowns, but was hoping he would lighten up. He may be exiled to spend his life in my frag tank. Any suggestions?
